ABSTRACT

A composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers, such as hair, comprising, in a medium suitable for dyeing,  
     a) at least one oxidation dye,  
     b) at least one fatty alcohol,  
     c) at least one associative polymer, and  
     d) at least one C 14 -C 30  alkyl sulphate; as well as the process for using this composition and multicompartment kits comprising the composition.

[0001] This application claims benefit of U.S. Provisional Application No. 60/502,218, filed Sep. 12, 2003.

[0002] Disclosed herein is a composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers. such as hair, comprising at least one oxidation dye, at least one fatty alcohol, at least one associative polymer and at least one C₁₄-C₃₀ alkyl sulphate.

[0003] It is known practice to dye keratin fibers, such as human hair, with dye compositions comprising oxidation dye precursors, generally known as “oxidation bases”, such as, ortho- or para-phenylenediamines, ortho- or para-aminophenols, and heterocyclic bases.

[0004] Oxidation dye precursors are compounds which are initially uncolored or only weakly colored and which develop their dyeing power on the hair in the presence of oxidizing agents, leading to the formation of colored compounds. The formation of these colored compounds may result either from an oxidative condensation of the “oxidation bases” with themselves or from an oxidative condensation of the “oxidation bases” with coloration modifiers, or “couplers”, which may be present in the dye compositions used in oxidation dyeing and are represented, for example, by meta-phenylenediamines, meta-aminophenols and meta-diphenols, and certain heterocyclic compounds.

[0005] The variety of molecules used, which include on the one hand the “oxidation bases” and on the other hand the “couplers,” can allow a very wide range of colors to be obtained.

[0006] Compositions which comprise oxidation dyes and that are mixed before use with an oxidizing agent can often be provided in the form of water-based creams conventionally comprising fatty alcohols and occasionally soaps. These creams may have a high fatty alcohol and crosslinked polyacrylic acid content in order to ensure the consistency and stability of the medium.

[0007] The present inventors, however, have noted that this high fatty alcohol content can lead to a change in viscosity of the tinctorial composition over time, which can be manifested in a reduction in the ease of mixing with the oxidizing agent and in an impairment of the usage qualities such as elimination on rinsing.

[0008] However, following substantial research, the present inventors have now found that oxidation dye compositions comprising at least one oxidation dye, at least one fatty alcohol, at least one associative polymer and at least one C₄-C₃₀ alkyl sulphate can have a satisfactory consistency and a viscosity which may be stable over time without the need to raise the concentration of fatty alcohols or to use other thickening agents of the crosslinked polyacrylic acid type.

[0009] This discovery forms the basis of the various embodiments disclosed herein.

[0010] Disclosed herein is thus a composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers, such as hair, comprising, in a medium suitable for dyeing,

[0011] a) at least one oxidation dye,

[0012] b) at least one fatty alcohol,

[0013] c) at least one associative polymer, and

[0014] d) at least one C₁₄-C₃₀ alkyl sulphate.

[0015] Further disclosed herein is a ready-to-use composition for the dyeing of keratin fibers comprising at least one oxidation dye, at least one fatty alcohol, at least one associative polymer, at least one C₁₄-C₃₀ alkyl sulphate and at least one oxidizing agent.

[0016] As used herein, the expression “ready-to-use composition” means the composition is intended for application as is to the keratin fibers; that is to say, it may be stored as is before use or may result from the extemporaneous mixing of two or more compositions.

[0017] Further disclosed herein is a process for the oxidation dyeing of keratin fibers, for example, human keratin fibers such as hair, comprising applying to the fibers at least one composition (A) comprising, in a medium that is suitable for dyeing, at least one oxidation dye, at least one fatty alcohol, at least one associative polymer, and at least one C₁₄-C₃₀ alkyl sulphate, the color being developed at alkaline, neutral or acidic pH, by means of at least one composition (B) comprising at least one oxidizing agent, which is mixed with the composition (A) at the time of use or which is applied to the fibers sequentially before or after composition (A), with or without intermediate rinsing.

[0018] Further disclosed herein are multi-compartment dyeing devices or multi-compartment kits for the oxidation dyeing of keratin fibers, for example, human keratin fibers such as hair. This device may comprise a first compartment comprising at least one oxidation dye, at least one fatty alcohol chosen from possibly oxyalkylenated and glycerolated fatty alcohols, at least one associative polymer, and at least one C₁₄-C₃₀ alkyl sulphate, and a second compartment comprising at least one oxidizing agent.

[0024] The at least one C₁₄-C₃₀ alkyl sulphate may, for example, be present in the composition disclosed herein in an amount ranging from 0.1% to 10% by weight, relative to the total weight of the composition, and further, for example, from 0.5% to 5% by weight, relative to the total weight of the composition.

[0025] Associative Polymers

[0026] The at least one associative polymer is a polymer whose molecules are capable, in the formulation medium, of undergoing association with one another or with molecules of other compounds.

[0027] For example, one type of associative polymers that can be used in the composition disclosed herein are amphiphilic polymers, i.e. polymers comprising at least one hydrophilic moiety which render them soluble in water and at least one hydrophobic region, comprising at least one fatty chain, by means of which the polymers interact and undergo assembly with one another or with other molecules.

[0093] The cationic associative polyurethanes that can be used in the composition disclosed herein may, for example, be chosen from cationic associative amphiphilic polyurethanes, which are water-soluble or water-dispersible.

[0094] The term “water-soluble” or “soluble in water” in relation to the cationic associative amphiphilic polyurethanes disclosed herein means that these polymers have a solubility in water at ambient temperature of at least 1% by weight; that is to say that, up to this concentration, no precipitate can be detected by the naked eye and the solution is perfectly clear and homogeneous.

[0095] Polyurethanes which are “water-dispersible” or “dispersible in water” are polymers which, when suspended in water, spontaneously form droplets having an average size, as measured by light scattering on a Coulter-type apparatus, ranging, for example, from 5 nm to 600 nm, and further, for example, ranging from 5 nm to 500 nm.

[0096] The family of cationic amphiphilic polyurethanes disclosed herein have been described in French Patent Application No. 0 009 609; this family may be represented by the general formula (IV) below:

R—X—(P)_(n)—[L—(Y)_(m)]_(r)—L′—(P′)_(p)—X′—R′  (IV)

[0097] wherein:

[0098] R and R′, which may be identical or different, are each chosen from hydrophobic groups and a hydrogen atom;

[0099] X and X′, which may be identical or different, are each chosen from groups comprising at least one amine functional group optionally bearing at least one hydrophobic group, or alternatively groups L″;

[0100] L, L′ and L″, which may be identical or different, are each chosen from groups derived from a diisocyanate;

[0104] n, m and p, which may be identical or different, are each integers ranging from 0 to 1000; and

[0105] wherein the molecule comprises at least one functional group chosen from protonated and quatemized amine functional groups and hydrophobic groups.

[0106] In one embodiment of the polyurethanes disclosed herein, the only hydro-phobic groups are the groups R and R′ at the chain ends.

[0107] For example, one family of cationic amphiphilic polyurethanes that can be used in the composition disclosed herein, for example, is the one corresponding to formula (IV) described above wherein:

[0108] R and R′, which may be identical or different, are each chosen from hydro-phobic groups,

[0114] The fact that n and p are 0 means that these polymers do not comprise units derived from a monomer comprising at least one amine functional group incorporated into the polymer during the polycondensation. The protonated amine functional groups of these polyurethanes result from the hydrolysis of excess isocyanate functional groups, at the chain end, followed by alkylation of the primary amine functional groups formed with alkylating agents comprising at least one hydrophobic group, i.e. compounds of the type RQ or R′Q, wherein R and R′ are as defined above and Q is chosen from leaving groups such as a halide, a sulphate, etc.

[0115] Yet another family of cationic amphiphilic polyurethanes that can be used in the composition disclosed herein, for example, is the one corresponding to formula (IV) above wherein:

[0117] X and X′, which may be identical or different, are each chosen from groups comprising at least one quaternary amine group,

[0118] n and p are equal to 0, and

[0120] The number-average molecular mass of the cationic associative polyurethanes may, for example, range from 400 to 500 000, further, for example, from 1000 to 400 000 and even further, for example, from 1000 to 300 000.

[0121] As used herein, the expression “hydrophobic group” means a radical or polymer comprising at least one chain chosen from saturated and unsaturated, linear and branched hydrocarbon-based chains, which may comprise at least one entity chosen from heteroatoms such as P, O, N or S and radicals comprising at least one chain chosen from perfluoro and silicone chains.

[0122] In one embodiment, the hydrocarbon-based radicals can be derived from a monofunctional compound.

[0123] For example, the hydrophobic group may be derived from a fatty alcohol such as stearyl alcohol, dodecyl alcohol or decyl alcohol. It may also be a hydrocarbon-based polymer such as, polybutadiene.

[0124] When X and/or X′ are chosen from groups comprising at least one group chosen from tertiary and quaternary amine groups, X and/or X′ may represent one of the following formulae:

[0125] wherein:

[0126] R₂ is chosen from linear and branched alkylene radical comprising from 1 to 20 carbon atoms, optionally comprising at least one entity chosen from saturated and unsaturated rings and an arylene radical, at least one of the carbon atoms possibly being replaced with a heteroatom chosen from N, S, O and P;

[0127] R₁ and R₃, which may be identical or different, are each chosen from linear and branched C₁-C₃₀ alkyl and alkenyl radicals and aryl radicals, at least one of the carbon atoms in said radicals possibly being replaced with a heteroatom chosen from N, S, O and P; and

[0128] A⁻ is a physiologically acceptable counter-ion.

[0129] The groups L, L′ and L″, which may be identical or different, each represent a group of formula:

[0130] wherein:

[0131] Z is chosen from 13 O—, —S— and —NH—; and

[0132] R₄ is chosen from linear and branched alkylene radicals comprising from 1 to 20 carbon atoms, optionally comprising at least one entity chosen from saturated and unsaturated rings and an arylene radical, at least one of the carbon atoms possibly being replaced with at least one heteroatom chosen from N, S, O and P.

[0133] In formula (IV), the groups P and P′, which may be identical or different, comprising at least one amine functional group, may represent at least one of the following formulae:

[0134] wherein:

[0135] R₅ and R₇, which may be identical or different, have the same meanings as R₂ defined above;

[0136] R₆, R₈ and R₉, which may be identical or different, have the same meanings as R₁, and R₃ defined above;

[0137] R₁₀ is chosen from linear and branched, optionally unsaturated alkylene groups which may comprise at least one heteroatom chosen from N, O, S and P, and

[0138] A⁻ is a physiologically acceptable counter-ion.

[0139] With regard to the meaning of Y, as used herein, the term “hydrophilic group” means a polymeric or non-polymeric water-soluble group.

[0140] For example, when the hydrophilic group is not a polymer, it may be chosen from ethylene glycol, diethylene glycol and propylene glycol.

[0141] When the hydrophilic group is a hydrophilic polymer, in accordance with one embodiment disclosed herein, it may, for example, be chosen from at least one of polyethers, sulphonated polyesters, and sulphonated polyamides.

[0143] A first type of compound involved in the preparation of the polyurethane of formula (IV) is a compound comprising at least one unit comprising at least one amine functional group. This compound may be multifunctional, but the compound may, for example, be difunctional, that is to say that, according to one embodiment disclosed herein, for example, this compound comprises two labile hydrogen atoms borne, for example, by a hydroxyl, primary amine, secondary amine or thiol functional group. A mixture of multifunctional and difunctional compounds in which the percentage of multifunctional compounds is low may also be used.

[0144] As mentioned above, this compound may comprise more than one unit comprising at least one functional group. In this case, it is a polymer bearing a repetition of the unit comprising at least one amine functional group.

[0145] Compounds of this type may be represented by one of the following formulae:

[0154] By way of example, this compound may be a fatty alcohol such as, stearyl alcohol, dodecyl alcohol or decyl alcohol. When this compound comprises a polymeric chain, it may be, for example, a-hydroxylated hydrogenated polybutadiene.

[0155] The hydrophobic groups of the polyurethane of formula (IV) may also result from the quaternization reaction of the tertiary amine of the compound comprising at least one tertiary amine unit. Thus, the hydrophobic groups can be introduced via the quaternizing agent. This quaternizing agent is a compound of the type RQ or R′Q, in which R and R′, which may be identical or different, are as defined above and Q denotes a leaving group such as a halide, a sulphate, etc.

[0160] The hydrophilic group termed Y in formula (IV) is optional. Specifically, the units comprising quaternary amine or protonated functional groups may suffice to provide the solubility or water-dispersibility required for this type of polymer in an aqueous solution.

[0161] Although the presence of a hydrophilic group Y is optional, cationic associative polyurethanes comprising such a group may, for example, be used.
